SPAM

My account has recently become flooded with SPAM. No matter how assiduously I go through the serpentine procedure (click-scroll-click for each and every one - it used to be just one click (just one)) to mark each of the 200-300 SPAM emails that I receive almost daily, the flood continues and all my requests for help from Zoho go unanswered (or are they lost in the SPAM flood?) I am finding the Zoho Anti SPAM procedure to be completely ineffective and their Customer Support to be non-existent. Is it me or them ????
